Why Your Resume Gets Rejected by ATS (And How to Fix It)

The most common reasons your resume gets rejected by ATS — file format, missing keywords, formatting issues, and header/footer problems — with specific fixes for each.

💡

Key Takeaways

Most resume rejections happen because of formatting issues, not lack of qualifications
ATS systems can't read tables, text boxes, images, or content in headers/footers
Missing keywords from the job description is the most common cause of low ATS scores
Always use standard section headings like 'Work Experience' and 'Skills'
Check your ATS score with a tool like ATSAlign before every application

You are qualified for the role. You spent hours on your resume. You applied and heard nothing. If this sounds familiar, an ATS filter is likely the culprit — not your experience.

ATS (Applicant Tracking Systems) automatically reject a large portion of applications before any human reviews them. Understanding exactly why this happens is the first step to fixing it.

Reason 1: Wrong File Format

The problem: You submitted a PDF, and the ATS cannot parse it correctly.

Not all PDFs are equal. PDFs saved from Word or Google Docs are text-based and usually parse well. But PDFs generated from design tools (Canva, Adobe Illustrator) are often image-based — the ATS sees a picture, not text, and extracts nothing.

The fix: Save your resume as DOCX and submit that unless the application specifically requires PDF. If you must use PDF, export it from Word or Google Docs — never from a design tool.

Reason 2: Complex Formatting

The problem: Your resume uses tables, columns, text boxes, or graphics.

ATS parsers read text linearly — left to right, top to bottom. When they encounter a two-column layout, they often merge both columns into a single stream of text, creating gibberish. Tables split your content into cells the parser cannot interpret correctly. Text boxes are frequently skipped entirely.

The fix: Use a simple single-column layout. No tables. No text boxes. No graphics or icons. It will look simpler, but it will parse perfectly.

Reason 3: Missing Keywords

The problem: Your resume does not contain the specific terms from the job description.

ATS systems do not infer meaning — they match text. If the job description says "Google Ads" and your resume says "paid advertising," that is a miss. If the JD says "data visualisation" and you wrote "built dashboards," that is a partial miss.

The fix: Read the job description carefully. Identify the specific tools, skills, and phrases mentioned. Include the exact terms in your resume — especially in your skills section and work experience bullets. Use ATSAlign's free ATS checker to see your keyword match score before applying.

Reason 4: Contact Information in Header or Footer

The problem: Your name, phone number, and email are in the document's header or footer section.

Many ATS systems skip headers and footers entirely. Your resume may be parsed as having no contact information, causing the application to be rejected or flagged as incomplete.

The fix: Move all contact information into the main body of the document — not in a header or footer.

Reason 5: Unconventional Section Headings

The problem: Your sections are named creatively instead of using standard labels.

ATS systems look for specific headings to categorise your information:

Work Experience (not "My Career Journey" or "Professional Story")
Education (not "Academic Background")
Skills (not "What I Bring" or "My Toolbox")

If the ATS cannot identify your sections, it cannot score your experience or education correctly.

The fix: Use standard headings: Skills, Work Experience, Education, Certifications, Projects.

Reason 6: The Job Title Does Not Match

The problem: Your most recent job title is not close enough to the role you are applying for.

Job title matching is heavily weighted in most ATS systems. If you are applying for a "Data Analyst" role but your last title was "Reporting Specialist," you may score lower than someone with the exact title — even if your work was identical.

The fix: If your title was an internal name that does not reflect standard industry terminology, add a clarification in your work experience. For example: "Reporting Specialist (Data Analyst equivalent)". Do not fabricate titles, but do contextualise unusual ones.

Reason 7: Experience or Education Does Not Meet Minimum Requirements

The problem: The job has hard minimum requirements — years of experience, specific degree — that your resume does not meet.

Most ATS systems have a knockout filter. If a job requires a minimum of 5 years of experience and your resume shows 2, you may be automatically filtered regardless of your qualifications.

The fix: Only apply for roles where you genuinely meet the minimum requirements. If you are slightly below the minimum, make sure your total relevant experience is clearly stated and your skills section is strong.

Reason 8: Inconsistent Dates in Work Experience

The problem: Missing dates, overlapping dates, or unusual date formats confuse the ATS experience parser.

The fix: Use a consistent date format throughout: "Jan 2022 – Mar 2024" or "January 2022 – March 2024." Include dates for every role and every degree.

Reason 9: Skills Are Listed Vaguely

The problem: "Experienced in various programming languages" tells the ATS nothing. It cannot match this to "Python" or "JavaScript."

The fix: List every skill explicitly. "Python, JavaScript, React, SQL, Docker" is far better than any descriptive phrase.

Check Your ATS Score Before Every Application

ATSAlign's free ATS checker identifies exactly which of these problems exist in your resume for any specific job. Upload your resume, paste the job description, and see your score plus a detailed list of missing keywords and issues — in 30 seconds, no signup required.

Most ATS rejections are fixable in under 15 minutes. The key is knowing what to fix.

Summary

ATS rejections are almost always caused by fixable technical issues: wrong file format, complex layout, missing keywords, or contact info in headers. None of these are experience gaps — they are formatting and keyword problems. Fix them, check your score, and you will immediately see more responses.
